Some of the fan base calls Applejack a back ground pony because she doesn't have as much character development or interesting personality traits as the other main five ponies. But honestly she's my favorite

Oh noes! Spread the message to tell the bronies are taking over DA! (Although nothing is wrong with that. This is not meant to offend any brony, only the fandom. Warriors is awesome. I am no longer a brony. Spread the word! It's the beginning of brony rule! Hallehjeauleh!+ Ido not support bronies.)

of God which is nice 'cause in my life seen anything like it: D HAVE TALENT.! (BTW I'm new here ._., And if you could comment / evaluate my profiu my prece ... oh please this is important because I want to know at what level I)

Those eyes...they're quite possibly the most beautiful shade of green I have ever seen! Her eyes are like big, sparkly emeralds. It's suddenly making me want to draw a character with big green eyes like AJ's here. Excellent work.

Here's what it is. Remember the monkeys in Hasbro that were in the marketing department, and only put Equestria Girls (which was made specifically FOR money so they could compete with their rivals) in select theaters? Well, they didn't get sacked, they're still running some of the merchandise. These monkeys noticed Applejack hasn't had as many lines as the others so they assume she's a background pony and exclude her from the stickers, McDonalds toys, and posters (all three of which have all the other five, and the stickers have Celestia and Luna too).

What the monkeys didn't seem to get was that Applejack appeared in the most episodes of any of the Mane 6. Of the 91 episodes, Fluttershy didn't appear in 14, Pinkie Pie, Rainbow Dash, and Rarity each didn't appear in 11, Twilight, the MAIN CHARACTER, didn't appear in 8, and Applejack didn't appear in 6. Also, she's the only one of the other mane 5 besides Twilight to be paired up with each of the other Mane 4 as the star of an episode (Rarity in Look Before You Sleep, Rainbow Dash in Fall Weather Friends, Fluttershy in Bats!, and Pinkie Pie in Pinkie Apple Pie)
